So I was thinking about this, and if we come to the conclusion a videogame is a piece of software intended for play, then can one single piece of software be multiple games?
On the opposite end, can the same videogame be multiple independent pieces of software?
To go deeper in this conversation but not in an abstract game, I've made you this gift, which I'm not sure if it is one videogame, four videogames, or no videogame at all. Hope you enjoy it! https://ricoalbe.itch.io/dunlaoalotro
